It depends on the question, but if the questions is sort of like "Person A and Person B shared 40 sweets in the ratio 3:5, how many sweets did Person A get" then you add 3 and 5 to get 8, and then you do 40 ÷ 8 to get 5 which is 1 in terms of the ratio. Then, you would multiply 5 by 3 to get 15 sweets. If it's a different type of question then let me know so I can help out :)

(0,-9) could be a solution
        
             
        
        
        
The area of every circle is        (pi) (radius²) .
Radius = 1/2 of the diameter, so the area of your circle is
                   (pi) x (8 cm)²  =  201 cm² .    (rounded)
(pi) is not 3 .   There's nothing wrong with approximating (pi), 
but 3 is more than 4.5% wrong, and that's too much.  There's 
no reason why  3.14  should be too hard to handle.
